Please Consider Sharing

In addition to the hot air balloon, the sexy little black dress and photography, the French may have inadvertently invented April Fools’ day, known as “poison d’avril” in France, literally, April fish day. Here’s what you need to know about this fishy day in France.

Poisson D’Avril: April Fools day in France

April fools day might be one of the most widely recognized non-religious holidays in the Western world.

Even the French, known for fashion, food and sophistication, love to play pranks and jokes on unsuspecting friends on April 1st.  But in France, there’s one traditional prank that not many other countries have, and it involves a fish.

1) In French, April Fools day is called “Poisson D’Avril”.

The literal translation of April fools is “dupe d’avril,” but no one ever uses this term for April fools day in France. 

Instead, it’s called April Fish, literally, “Poisson d’Avril” [PWAH-Sone DAH-Vril]. 

I’ll explain later why it’s called “April Fish”. 

Why is April first called April Fish 'Poisson d'avril' in France?

2) How is Poisson d’Avril celebrated in France (modern times)? 

The fish on the back prank!

A common prank, especially among school-aged children, is to draw or print out a fish and stick it to the back of unsuspecting victims. Once the unfortunate fool discovers the fish taped to their back, the kids have a good yuck and scurry away, laughing as they shout, “Poisson d’avril, Poisson d’aviril.”

Adults and Even businesses in France play pranks and hoaxes:

 It’s not just kids who love pranking their friends and parents. Adults like to get in on the action, too, from simple pranks on friends, family and co-workers to elaborate fake news hoaxes and marketing pranks.

  • In 2018, the news outlet Nice-Matin published an April fools day hoax article about the famous blue chairs along the beautiful “Promenade des Anglais,” stating that they were replaced by mundane yellow chairs.
  • In 2017, news outlet Var-Matin played an especially cruel hoax on April first by reporting that the traditional French game of Boules would be banned.
  • Even RATP, the French public transport network, gets in on the act by renaming some of Paris metro stations using wordplay and puns. For instance, RATP renamed the station “Opéra” to “Apéro,” which means appetizer.”Télégraphe” metro station became “#Tweet” and “Quatre Septembre” became “1er Avril”. And to ensure the pranks get some excellent marketing and publicity, RATP uses the hashtag #Stationdavril

j’aurais and Jaurès are pronounced the same. The metro sign above reads, “If I had known, I would not have come,” a wordplay on Jaurès the name of the station and J’aurais “would have.”

4) How French April Fools day (Poisson d’Avril) was celebrated in the past!

At the beginning of the twentieth century, people in France sent adorably comical postcards on April 1st. The cards usually wished friends and family good fortune, love, friendship and or happiness! A tradition that isn’t so popular today.

5) April Fools Day may have been invented in France around the 1600s.

Although different cultures have celebrated April Fools’ Day for several centuries, its exact origins remain a mystery. There is, however, one theory that stands out from the rest.

Many historians believe playing pranks and tricking people on April first can be traced back to “Le Grand Tour De France” in 1564 and French King Charles the IX.

Le Grand Tour De France:

Catherine de Medicis wanted her son, King Charles, the IX of France, to get to know his kingdom, so she arranged “Le grand tour de France.” 

For two years, beginning January of 1564 through May 1st, 1566, King Charles IX, his mother and an entourage of nearly 2000 people travelled over 400 kilometres through some of the most remote border areas of the French kingdom.

April 1st was one of several New Year dates before the Gregorian Calendar.

Various diocese scattered across the French kingdom celebrated the New Year on different dates, which wasn’t unusual at the time. Throughout recorded history, most cultures used different dates that were central to their lives or dates tied to religion. 

For example, the Diocese in Savoie France celebrated New year on Christmas day. Other regions celebrated on the 1st of March or Easter Sunday (which is a moveable date). The most popular or most celebrated New years’ date at that time was the 25th of March, the Feast of the Annunciation. However, because it landed during a holy week, the actual festivities didn’t begin until the first of April.

King Charges wanted to standardize the New Years’ date.

Fed up with the multiple New Year dates, which was confusing and caused an administrative fiasco, King Charles IX issued the  (Édit de Roussillon) on August 9th, 1564. It decreed that the New Year would begin on January 1st throughout the entire French Kingdom. 

But France wasn’t the first to adopt this date. At the time, the German Emperor had already fixed January 1st as the New Year’s date. 

It wasn’t until the Catholic Pope Gregory XIII introduced his Gregorian calendar (the same one we all use today) that the change in New Years’ date slowly starts to take hold of the western world. 

6) French peasants and farmers may have started the tradition of playing pranks:

Even though the French King and the pope switched over to the Gregorian calendar, many French peasants continued to celebrate New Years on the old dates, especially April 1st.

Either because they didn’t want to switch or because they weren’t aware of the change to January 1st. 

News travelled slowly back then. 

One theory as to why pranks play such a significant role on April first dates back to Medieval times when people would visit friends, family and neighbours and give gifts or tithes for the April 1st New Year.
After King Charles IX switched to the newly decreed January 1st New Year’s date, some French peasants ridiculed, teased and tried to confuse late adopters who clung to the old April 1st date. They would drop in, sometimes bringing fake gag New Year gifts.

7) Why do French people call April First “April Fish?”

There are many theories about how the fish became the symbol of April fools day in France (and a few other countries), but these are the ones I know about.

One theory as to why April first is called “April Fish” in France has to do with fishermen. Historically, fishermen were prohibited from fishing during April because it was the breeding period of fish. Some people would give these poor fishermen friends a fake fish as a funny prank. 

Another plausible explanation is that since most of Europe celebrated the New year during Lent, where people were only allowed to eat fish, people gave fish as gifts for new years.

April Fools Day Today

While the story of April fools day starting in France is just one of many legends, we may never know how it really started. However, it’s clear that it’s here to stay.

Currently, playing pranks on April 1st is celebrated in many countries around the world, including Switzerland, Denmark, Italy, Canada, the UK and more. Each with their own little idiosyncrasies.

But France, Italy and the French-speaking province of Quebec, Canada, are the only countries that call this day April Fish and have the custom of sticking paper fish on the backs as a prank.

One last thing. If you’re ever in France on April first, keep your eye out for fish-shaped chocolates sold in stores through Easter.

April Fools! Or is it?
